Dell PowerProtect Data Domain, versions 7.7.1.0 through 8.7, LTS2026 release version 8.6.1.0 through 8.6.1.10, LTS2025 release version 8.3.1.0 through 8.3.1.30, LTS2024 release versions 7.13.1.0 through 7.13.1.70 contain an improper limitation of a pathname to a restricted directory ('Path Traversal') vulnerability. An unauthenticated attacker with remote access could potentially exploit this vulnerability, leading to unauthorized access to the system. This is a critical severity vulnerability as it allows an attacker to take complete control of system; so Dell recommends customers to upgrade at the earliest opportunity.
